Hi. I will start building the Oddwatt amps and I am trying to figure out the best way to house the various components (caps, resistors, diodes, etc.).In the past I have done point to point using terminal strips.However this time I would like to place the components on a board to get a cleaner project.I purchased an epoxy glass reinforced prototyping breadboard and a turret board.The breadboard lends itself easier because it is predrilled with many holes.

Question: is it OK to use the breadboard and solder the components on one side of the board?I tried with one resistor and it holds it firmly. But where I soldered it leaves a film (is it the rosin flux and/or part of the board?) and I wonder if this compromises the soldered connection.

Hi, I believe you are referring to a printed circuit board PCB or a prototyping board, not a breadboard. A breadboard is used to try various connections and is composed of lots of rows of holes that use push pin connectors. it is not for permanent connections. PCBs come in many varieties....undrilled, plated one side only, plated holes and so on. I use them all the time for builds. I prefer the fiberglass reinforced ones, but the phenolic ones are OK if you don't stress them physically. I also like to solder both sides of the boards when possible. Like with resistor leads.

Just be aware that hot components will need lifting away from the board.It is useful for bias pots etc. Just be aware of voltages used on the board.I still prefer point to point turret board: because you are restricted to copper tracks on PCB.Also you have the board insulation (Type) and modifications can be messy.But many old amps used PCB's eg the Mozart.https://www.google.co.uk/search?q=Pye+m ... dsQOeuTAWM:
